If radius of a hemisphere is 14 cm find its

(¡.) Curved surface area

(¡i) Volume [pi 22/7]​

                                                                                                   

║⊕ANSWER⊕║

SOMETHING YOU SHOULD KNOW FIRST

Curved surface area of the hemisphere = 2πr²

Total surface area of the hemisphere = 3 πr²

Volume of the hemisphere = 2/3 πr³

Curved surface area of the hemisphere

$2\pi r^{2}$

=> $2 * \frac{22}{7} * 14 * 14$

=> $1232 cm^{2}$

Volume of the hemisphere

$\frac{2}{3} \pi x^{3}$

=> $\frac{2}{3} * \frac{22}{7} * 14 * 14 * 14$

=> $5749.33 cm^{3}$

C.S.A. ⤵

$radius = 14cm \\ csa = 2\pi {r}^{2} \\ = > 2 \times \frac{22}{7} \times 14 \times 14 \\ = > 44 \times 28 \\ = > 1232 {cm}^{2}$

VOLUME ⤵

$volume = \frac{2}{3} \pi {r}^{3} \\ = > \frac{2}{3} \times \frac{22}{7} \times {14}^{3} \\ = > \frac{44}{3} \times 392 \\ = > 5749.33 {cm}^{3}$

have a great day
